MACHINE FOR FINISHING THE NECKS OF BOTTLES, JARS, 80C.

SPECIFICATION forming part Of Letters Patent NO. 404,311, dated May 28, 1889.

Application filed October 24, 1888. Serial No. 289,023- (No model.)

.To aZZ whom it may concern:

Be it known that we, HARRY SEMPLE and CHARLES N. BRADY, citizens of the United States, residing, respectively, at Steubenville,

in the county of Jefferson and State of Ohio,

and at \Vashington, in the county of ashingtou and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Finishing the Necks of Bot- IO tles, Jars, &c. and we do hereby declare the following to be a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The object we have in view is an improvement upon a machine described in the patent dated June 12, 1888, and numbered 884,290, granted to Harry Semple; and the improvement therein consists, mainly, in changes of construction, for the purpose of the adaptation of the machine for finishing the inside as well as the outside of the necks of jars and bottles of various kinds and shapes and other similar articles, and in the means for holding such jars, bottles, or other articles while under the operation of finishing, and in various other changes in construction, such as will be hereinafter more fully explained and specifically claimed.

The drawings hereto annexed will show clearly the mechanism employed, and in each figure the same letters will be used to designate the same parts.

In the drawings, Figure 1 is a side eleva- 3 5 tion of the machine as adapted for use; Fig.

2, an end elevation of the head and its attachments; Fig. 3, a side elevation of the same; Fig. 4, an end elevation of the means employed to produce rotative movement back and forth; Fig. 5, a side elevation of the modified machine, adapted to use finishing-fingers Fig. 6, an end elevation of the arm-support for the machine illustrated in Fig. 5; Fig. 7, a side elevation of the same, and Fig. 8 an end elevation of the modified means for pro ducing rotative movement.

The operative parts of this machine are mounted upon or attached to a suitable table or frame, A, upon which is mounted a shaft,

is provided with a removable plug, B. Upon B, which is journaled in standards C O and this shaft is placed an arm-support, D, provided at its front with a collar, a, by means of which the support D is secured to the shaft B in any suitable manner and has the same rotative movement or back-and-forth motion which the shaft has. The arm-support is open to the rear of such collar of a size to permit the sleeve E, hereinafter described, to be moved back and forth within such open space, and has wings a, preferably three in number, each made in two parts with an open space between. To the upper eornersof these arms a the arms F F F, preferably three in numher, are pivoted. These arms have avertical or n earl y-vertical limb, 0, preferably provided with a friction-roller, d, which fits into a reccss or groove, 6, in said sleeve. These arms have also front limbs, c, bent down toward the shaft B, and are provided at the outer 7c ends with a knuckle-joint, f, to which are pivoted the sockets g, into which are inserted the jaws G, preferably of the construction shown, held in place within the sockets by suitable means, a thumb-screw being shown, and these jaws extend forward nearly as far as the front end of the plug. These arms are shown with weighted heads f at the rear.

Motion back and forth is given to the friction-rollers d, and through them to the arms F F F, by means of the sleeve E, which slides upon the shaft B, which is of sufficient length to afford space for the groove e and for the reception of the'upper part of a clutch, H, by means of which the sleeve is moved. The lower part of this clutch is held in position upon a rod, 1, by pins or collars on each side of it, and this rod passes through the standards O and one or more standards, O and O This rod has mount-ed upon it a standard, J, screw threaded in its lower part, through which a screw portion of the rod I passes, which rod is adjusted conveniently by a handwheel.

Another rod, K, passes over the upper parts 5 of the standard 0 and the standard;J, and to the inner end of this red the bottom of the bottle-holder L is fastened in any removable way. Movement of this bottle back and forth is made conveniently by a hand-piece or colzoo lar, M, secured to said rod. WVhen this collar is moved in the direction toward the jaws 1?, it strikes again st the upper end of the standard .l and moves the bottle toward the jaws G. At the same time the red I is moved in the same direction, carrying the clutch ll along, the clutch moving the sleeve E, and the movement of the sleeve moving the arms 1 F F and the jaws G. This red I is adjusted so as to place the necks of the bottles then separated sufficientlyfrom the jaws intended to receive such necks, that when the plug enters the neck of the bottle the movement of the rod 1, clutch ii, and the sleeve E causes the jaws to close down upon the neck of the bottle and hold it fast. hen the neck is finished, the rodsI and K are moved back by the hand, which withdraws the neck of the bottle from the jaws. At the same time the jaws are separated through the action of the clutch and sleeve upon the arms F F F. It will be understood that the adjustable jaws G are to be of a variety of forms to suit the various kinds of bottles, and that the plug 13' is also to be of avaricty of forms and sizes for the same purpose. It is essential for the work desired that the jaws should have a retative n'lovement back and forth, and this is conveniently accomplished by means of a drive-pulley, N, whose shaft N is pivoted between hangers O, and carries at one end an arm, I, pivoted to an arm, P, which arm. pivoted to the arm of a toothed segment-lever, Q, the teeth of which lever engage with those of a pinion, S, secured upon the shaft 1%. The rotation, therefore, of the drive-pulley gives a rotat-ive movement back and forth of the shaft 13, the plug 13, and the jaws G. It will be observed, also, that while only one side of a machine has been described for finishing the neck of only one bottle, the shaft 13 requires only to be lengthened, and the parts already described to be placed at the other end of the machine, as shown in Fig. 1, and it becomes a double machine with the capacity of finishing the necks of two bottles at the same time.

It may be desirable, particularly for jars and wide-mouthed bottles with a shape of the neck inside similar to or different from that of the outside, or ware with a shape inside of the neck which would not permit a solid plug to be withdrawn, to make some changes in the construction, in which. case the modifications found illustrated in Figs. 5, G, and 7 will be found convenient. In this instance a three-arm support, l),made as shown in Fi g. 5, is secured through its collar to the shaft 13 near its front end.

The arms I F" F' are each pivoted to an extremity of one of the arms a of the support in such away as to have a radial motion toward and away from the shaft. The forward end of each arm has a pendent forked portion, 1, a little distance from the end, adapted to permit the arm of the fingers G to move radially up and down between the forks mentioned.

The sleeve E in this instance has its front portion move over the cut-away rear part of the arn'i-support, and in such front portion carries in a groove, c,the upper rounded end of the bent lever, whose arm carries the re movable fingers G, which lever is pivoted at its bent portion in the supports D. These fingers are made of any desirable size or form to suit the purpose required, but preferably of the form shown, with curved fronts and round shanks, so as to be turned to present their faces differently.

It is to be understood that in the operation as first described of the machine the bottle is placed in the socket at the end of the rod K, which socket should nearly or quite cover the body of the article, leaving the neck protruding. In this position the neck heated sufficiently in the usual way, and the rod K placed in position and the bottle immediately moved forward so that the plug enters the opening in the neck, and the neck passes over such plug until the frontpart of the neck strikes against the shoulder a, and is thereby made uniform and smooth. The movement into this position of the neck of the bottle causes the jaws to close upon its outside by the means previously described. This rotative movement back and forth of the plug and jaws by the means before described causes the inside and the outside and the end of the neck to be finished rapidly, smoothly, and regularly. It will be understood that the adjustable character of both the plug and the jaws allows a great variety of sizes and forms of these parts to be used for various kinds of bottles, and the same is also true of the bottle-sockets, which may be made of all shapes and sizes to correspond with the bottles to be placed within them.

In the operation of this modification the neck of the jar or bottle is moved forward so that the fingers enter the opening in it, and below the outer end of the arms 1* l l1, separated sufiiciently for the purpose by the adjustment of the rod I, and when the neck has so entered by the movements before recited of the clamp and the sleeve, with a suitable loose connection between the arms F 1 1 and the bent lever, the fingers and said arms are brought toward each other and hold the neck of the bottle or jar between them and up against a shoulder, (1?, in the arms F 11 11". Such a loose connection is shown in a spur, 2, attached to the inner bend of the bent lever, with its outer end entering the jaws of a spur, 3, attached to the head or inner end of the arms 1 1* F. \Vhen the neck is finished, the fingers and arms are separated and the neck released, as before explained.

It follows that with suitable fingers and arms the inside of the neck may be finished to conform to the outside or not to conform to it, as desired, and that the necks of fruit-jars and others and wide mouthed bottles and other similar articles can be finished rapidly and accurately, and this form of apparatus is particularly adapted for the finishing of fruit-jars, such as shown in Fig. 2. In this instance, also, the arms may be arranged so as to be fixed in position radially by omitting the connection with the finger-lever and simply placing a leaf-spring upon the outside of the same, so as to hold them in position with little positive pressure.

Rotative movement may be given by the mechanism before described, or by that modification shown in Fig. 5, where an eccentric 011 the end of the pulley-shaft is pivoted to the lower end of the pivoted toothed segment.

It is to be understood that in the operation of the machine the bottle is placed in the socket at the end of the rod K, which socket should nearly or quite cover the body of the article, leaving the neck protruding. In this position the neck is heated sufficiently in the usual way, and the rod K placed in position, and the bottle immediately moved forward so that the plug enters the opening in the neck, and the neck passes over such plug until the front part of the neck strikes against the shoulder a, and is thereby made uniform and smooth. The movement into this position of the neck of the bottle causes the arms to close upon its outside by the means previously described.

The rotative movement back and forth of the plug and jaws by the means before described causes the inside and the outside and the end of the neck to be finished rapidly, smoothly, and regularly. It will be understood that the adjustable character of both the plug and jaws allows a great variety of sizes and forms of these parts to be used for the various kinds of bottles, and the same is also true of the bottles sockets, which may be made of all shapes and sizes to correspond with the bottles to be placed within them.

The operation is substantially the same where jars, wide-mouthed bottles, or like ware are used with finishing-fingers, which enter the the desired internal shape. In this way the necks of all kinds of bottles and other like articles can be finished quickly, uniformly, and perfectly, so as to require no grinding or other finishing, and the work can be done by unskillful boys.

Having thus described our invention, what we desire to claim and secure by Letters Patent is- 1. In a machine for finishing the necks of bottles, jars, or other like articles, the combination of means to hold the outside of the neck and finish the inside of the same, adapted to have a rotative movement back and forth, a rod provided with a socket for holding, presenting, and withdrawing the bottle, jar, or other article from the plug and jaws, and another rod adapted to regulate the distance of travel between the bottle, jar, or other article and the plug and jaws, substantially as described.

2. In a machine for finishing the necks of bottles, jars, and other like articles, the combination of an upper rod provided with a stop to carry the socket for the bottle, jar, or other like article, adjustable supports to hold said rod at the desired elevation, and a lower rod carrying a vertically-adjustable screw-- threaded standard and a clutch, substantially as and for the purpose described.

3. In a machine for finishing the necks of bottles, jars, or other like articles, the combi nation of an upper rod to carry the socket for the bottle, jar, or other like articles, a socket for the same, an adjustable lower rod carrying a standard and a clutch, a sleeve upon a shaft, a shaft having an adjustable plug, and a train of gears to give a rotative movement to the shaft, substantially as described.

4. In a machine for finishing the necks of bottles, jars, or other like articles, the combination of a rod to carry the bottle, jar, or other article, another rod to carry a clutch, a sleeve, and an arm-support upon a shaft, and arms and fingers to hold and finish the necks of such bottles, jars, orother articles, substantially as described.
